Description

Technical Field

[0001] This application relates to the field of channel seepage prevention technology, specifically a channel seepage prevention engineering device. Background Technology

[0002] Canal seepage prevention technology is a crucial aspect of water conservancy projects, primarily used to reduce water loss during transportation. Currently, canal seepage prevention technologies mainly include various methods such as concrete lining, geomembrane seepage prevention, and asphalt seepage prevention. Among existing methods, concrete lining achieves seepage prevention by laying a concrete layer on the canal surface. Its advantages are good durability and high strength, but its disadvantages include long construction period, high cost, and susceptibility to cracking due to temperature changes, leading to leakage. Geomembrane seepage prevention uses geomembranes made of polymer materials laid on the canal surface. Its advantages are good seepage prevention effect and simple construction, but its disadvantages include susceptibility to external damage and poor durability. Asphalt seepage prevention involves coating the canal surface with asphalt material. Its advantages are low cost and fast construction, but its disadvantages include poor weather resistance, easy softening at high temperatures, and easy cracking at low temperatures.

[0003] In summary, existing technologies still suffer from problems such as poor sealing, low durability, and low construction efficiency. To address these issues, a channel seepage prevention engineering device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a channel seepage prevention engineering device that has advantages such as sealing and durability, solving the problems of sealing, durability, and construction efficiency in channel seepage prevention projects.

[0005] To achieve the above objectives, this application provides the following technical solution: a channel seepage prevention engineering device, comprising a channel body, a support layer, a seepage prevention layer and anchor nails, wherein the support layer is laid on the surface of the channel body, the seepage prevention layer covers the surface of the support layer, the anchor nails penetrate the seepage prevention layer and the support layer and are fixed to the channel body, and the surface of the seepage prevention layer is coated with a silicon carbide wear-resistant coating.

[0006] The above scheme provides structural support and disperses external forces by setting up a support layer. By setting up an anti-seepage layer, a continuous anti-seepage surface can be formed by splicing and combining the anti-seepage layer. By setting up anchor nails, the anti-seepage layer and the support layer can be firmly fixed to the channel base, thereby achieving the purpose of efficient anti-seepage. The anti-seepage layer is made of high-molecular composite material, which has the advantages of strong weather resistance and is not easy to age or break. By compounding a silicon carbide wear-resistant coating on the surface of the anti-seepage layer, the surface erosion resistance can be enhanced and the service life of the anti-seepage layer can be extended.

[0007] Furthermore, the side of the seepage-proof layer is provided with an overlapping structure, including a connecting convex plate on one side and a connecting concave plate on the other side. A T-shaped connecting block is fixedly connected to the bottom of the connecting convex plate, and a T-shaped connecting groove is opened inside the connecting concave plate. The adjacent seepage-proof layers are joined by embedding the T-shaped connecting block into the T-shaped connecting groove to achieve mortise and tenon splicing.

[0008] The above solution uses a mortise and tenon joint structure to embed T-shaped connecting blocks into T-shaped connecting grooves, which can achieve seamless splicing of the anti-seepage layer, eliminate the risk of leakage at the joints, and the modular design facilitates construction and installation, making it especially suitable for large-span channel projects.

[0009] Furthermore, a metal protective cap is provided at the perforation of the anchor nail, and sealant is filled between the edge of the metal protective cap and the waterproof layer.

[0010] The above solution, by setting up a metal protective cover and sealant, can form a double seal, preventing leakage or corrosion caused by stress concentration at the anchor bolt perforation point, and improving the long-term sealing performance of the anchor point.

[0011] Furthermore, the impermeable layer is a PE geomembrane, and the supporting layer is a lightweight foamed concrete layer.

[0012] The above solution utilizes a PE geomembrane and a lightweight foamed concrete layer. The lightweight support layer reduces the channel load, while the PE membrane provides high chemical stability, making it suitable for corrosive environments.

[0013] Furthermore, the impermeable layer is a PVC geomembrane, and the supporting layer is a lightweight foamed concrete layer.

[0014] The above scheme utilizes a PVC geomembrane and a lightweight foamed concrete layer. The PVC geomembrane has good flexibility and can adapt to channel deformation, while the lightweight concrete can reduce foundation pressure.

[0015] Furthermore, the supporting layer is a regular concrete layer.

[0016] The above scheme, which uses PE geomembrane and ordinary concrete layer, has the advantages of high strength support and prevention of foundation settlement and cracking, and can be used for heavy-duty channels.

[0017] Furthermore, a steel mesh is embedded inside the ordinary concrete layer.

[0018] The above scheme, by setting up a steel mesh, can significantly improve the crack resistance of ordinary concrete layers, making it suitable for channels in earthquake zones or frost heave areas.

[0019] Furthermore, the impermeable layer is a multi-layer design, with the upper layer being a PE geomembrane and a silicon carbide wear-resistant coating, the lower layer being a PVC geomembrane, and a waterproof adhesive layer filling the space between the PE geomembrane and the PVC geomembrane. The supporting layer is a lightweight foamed concrete layer.

[0020] The above solution, which combines PE geomembrane and PVC geomembrane, can form a double-layer seepage barrier, creating a redundant seepage barrier that can still prevent leakage even if a single layer is damaged. It is suitable for high-end seepage prevention scenarios.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This channel seepage prevention engineering device, through its layered design, ensures uniform stress on the seepage prevention layer, avoiding localized damage. The seepage prevention layer can be seamlessly spliced ​​through splicing and assembly, eliminating the risk of leakage at joints. Simultaneously, its modular design facilitates construction and installation, making it particularly suitable for large-span channel projects. The support layer can be made of lightweight foamed concrete or ordinary concrete, while the seepage prevention layer can be made of PE geomembrane or PVC geomembrane, adapting to different engineering needs (such as ecological landscaping, corrosive environments, and channels with high seepage risk). The silicon carbide coating resists erosion, and the metal protective cover provides corrosion protection, reducing failures caused by physical wear. Finally, the double-layer seepage prevention design provides fault redundancy, significantly extending service life. Attached Figure Description

[0033] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a channel seepage prevention engineering device includes a channel body 1, a support layer 2, a seepage prevention layer 3, and anchor nails 9. The support layer 2 is laid on the surface of the channel body 1, and the seepage prevention layer 3 covers the surface of the support layer 2. The anchor nails 9 penetrate the seepage prevention layer 3 and the support layer 2 and are fixed to the channel body 1. The surface of the seepage prevention layer 3 is coated with a silicon carbide wear-resistant coating 14. By setting the support layer 2, structural support can be provided and external forces can be distributed. By setting the seepage prevention layer 3, the seepage prevention layer 3 can be spliced ​​and combined to form a continuous seepage prevention surface. By setting the anchor nails 9, the seepage prevention layer 3 and the support layer 2 can be firmly fixed to the channel base surface, thereby achieving the purpose of efficient seepage prevention. The seepage prevention layer 3 is made of high-molecular composite material, which has the advantages of strong weather resistance and is not easy to age or break. By coating the surface of the seepage prevention layer 3 with a silicon carbide wear-resistant coating 14, the surface erosion resistance can be enhanced and the service life of the seepage prevention layer 3 can be extended.

A T-shaped connecting block 401 is fixedly connected to the bottom of the connecting convex plate 4. A T-shaped connecting groove 501 is opened inside the connecting concave plate 5. Adjacent seepage-proof layers 3 are joined by the T-shaped connecting block 401 embedded in the T-shaped connecting groove 501 to achieve mortise and tenon splicing. Through the mortise and tenon splicing structure, the T-shaped connecting block 401 is embedded in the T-shaped connecting groove 501, which can achieve seamless splicing of the seepage-proof layers 3 and eliminate the risk of leakage at the joint. At the same time, the modular design facilitates construction and installation, and is especially suitable for large-span channel projects. A metal protective cover 10 is set at the perforation of the anchor nail 9. The edge of the metal protective cover 10 and the seepage-proof layer 3 are filled with sealant 11. By setting the metal protective cover 10 and the sealant 11, a double seal can be formed to prevent leakage or corrosion caused by stress concentration at the perforation of the anchor nail 9, which can improve the long-term sealing of the anchor point. The anchor nail 9 and the metal protective cover 10 are made of uniform stainless steel.

[0035] like Figure 1 and Figure 4 As shown, this embodiment is suitable for use in sewage irrigation channels. This utility model provides a technical solution: preferably, the seepage-proof layer 3 is a PE geomembrane 6, and the support layer 2 is a lightweight foamed concrete layer 12.

[0036] In this embodiment, by using PE geomembrane 6 and lightweight foamed concrete layer 12, PE geomembrane 6 can provide high chemical stability and is suitable for corrosive environments, while lightweight support layer 2 can reduce pressure on the foundation and is suitable for soft soil foundations with insufficient bearing capacity, and can be used for sewage irrigation channels.

[0037] The working principle of the above embodiment is as follows: In use, a lightweight foamed concrete layer 12 and a PE geomembrane 6 are laid sequentially on the surface of the channel body 1. After the laying is completed, anchor nails 9 are inserted through the PE geomembrane 6 and the lightweight foamed concrete layer 12 and fixed into the channel body 1. After the insertion is completed, a metal protective cover 10 is pasted on the surface of the anchor nail 9, and sealant 11 is filled between the edge of the metal protective cover 10 and the seepage prevention layer 3. After filling is completed, the channel body 1 is ready.

The lightweight concrete can reduce foundation pressure and can be used for ecological landscape channels.

[0041] The working principle of the above embodiment is as follows: In use, a lightweight foamed concrete layer 12 and a PVC geomembrane 7 are laid sequentially on the surface of the channel body 1. After the laying is completed, anchor nails 9 are inserted through the PVC geomembrane 7 and the lightweight foamed concrete layer 12 and fixed into the channel body 1.

[0044] In this embodiment, by setting up a steel mesh 1301, the crack resistance of the ordinary concrete layer 13 can be greatly improved, making it suitable for channels in earthquake zones or frost heave areas. By using a PE geomembrane 6 with the ordinary concrete layer 13, the ordinary concrete layer 13 has the advantages of high-strength support and preventing foundation settlement and cracking, and can be used for cross-road channels.

[0045] The working principle of the above embodiment is as follows: When in use, a steel mesh 1301 is set on the surface of the channel body 1.

[0048] In this embodiment, the combination of PE geomembrane 6 and PVC geomembrane 7 can form a double-layer seepage barrier, which can form a redundant seepage barrier. Even if a single layer is damaged, it can still prevent leakage. At the same time, the waterproof adhesive layer 8 fills the gaps, which can reduce the leakage rate. The lightweight foamed concrete layer 12 can reduce the load and can be used in channels with high risk of high cold and high seepage.

[0049] The working principle of the above embodiment is as follows: In use, a lightweight foamed concrete layer 12 is laid on the surface of the channel body 1.
